Tooth brush



Jan. 23, 1940. w. E. BEHRING TOOTH BRUSH Filed April 21, 1938 v EIwucmtom MLL/AM EBEIIR/NG C mum;

I Patented Jan. 23, 1940 uni-res STATES PATENT OFFICE 4 Claims.

This invention relates to tooth brushes, and has for one of its objects the production of a simple and efllcient means for facilitating the feeding of tooth paste to the bristle portion of the brush,

and also for efllciently closing the tooth paste ejecting opening so that the ejecting opening may be properly closed to prevent the entrance of-air which would cause hardening of the tooth paste within the tooth paste tube which is adapted to be carried by the handle.

' A further object of this invention is theproduction of a simple and efficient combination valve and handle cover which is so mounted upon the handle of a brush, such as a tooth brush and the like, as to retain the tooth paste tube within the handle of the brush and also constitute a closure valve for the paste ejecting opening or port which is located adjacent the bristles of the brush.

Other objects and advantages of the present 2(i'invention will appear throughout the following specification and claims.

In the drawing: Figure 1 is a bottom plan view of the tooth brush;

I Figure 2 is a longitudinal sectional view through the tooth brush, a portion thereof being shown in elevation;

Figure 3 is: a bottom plan view of the tooth brush, the handle cover being shown in an open position;

Figure 4 is a transversesectional view taken on line '44 of Figure 2;

Figure 5 is a bottom plan view of a modified form of the tooth brush;

Figure 6 is a transverse sectional view taken on .line 66 of Figure Figure 7 is a fragmentary bottom plan view of the modified form 0! brush shown in Figure 5. with the valve extension of the handle cover man open position.

By referring to the drawing, it will be seen that ill designates the handle of the tooth brush which is provided with an elongated longitudinally extending socket I I having a threaded opening l2 at a one end which communicates with an outwardly extending channel or port I3. This channel or pdrt I3 is provided with a discharge opening l4 adjacent the base of the inner group oi bristles it carried by the brush head it, as shown in Figtires 2 and 3..

A cover plate I! is pivotallymounted, as at l8,

position against accidental opening. This handle paste from the discharge opening l4, the handle and lower the head i6. When'pressure is brought with a detent 20 near its outer end for fitting in a socket 2i formed in the handle Ill, as shown in Figures 2 and 3, to hold the handle I! in a closed I1 is provided with'a reduced valve extension 22 5 at the end opposite the detent 20', which reduced valve extension 22 is adapted to overhang the discharge opening i4 when the handle I1 is in a closed position such as is shownin Figure 1. thereby completely sealing the opening l4 pre- 10 venting the discharge of tooth paste therefrom, and also preventing the entrance of air which would tend to harden the tooth paste within the channel 13. The threaded neck 23 of the tube i9 is adapted to thread into the threaded-socket ll i2 and the tube i9 lies within the channel II, as described. When it is desired to discharge tooth ll is swung to the position shown in Figure 3, uncovering the discharge opening l4 and the tooth at brush is held in a position to elevate the handle to bear upon the tube IS with the thumb or flngers of the operator, the paste will pass out through the tube and passage i3, out through the discharge opening l4, and over and upon the bristies l5 carried by the head I 6. When a sufiicient amount of paste has been discharged, the cover I! maybe swung to the position shown in 1 Figure 1', the detent 20 looking in the socket 2| 30 and the tooth brush will then be ready for use.

In Figures 5 and 6, I have shown a modified form 01 the invention, wherein the handle of the brush lsindicated by the numeral 24, the handle ing cover 21 movable longitudinally of the handle 24. The cover 21 is provided with a valve extenso sion or neck 28 which is adapted to cover the tooth paste discharge port or opening 29 when the cover 21 is in the position shown in Figure 5. The cover 21 may be moved in the direction of the arrow shown in Figure 5 for uncovering the port 4,5 29 in a manner as shown in Figure '7.

It should be understood that the present type of brush may be used for holding paste of any character without departing. from the spirit of their:- vention, since it is not desired to limit the present an invention to a type of brush merely for holding tooth paste.

Having described the invention, what is claimed 1. A'fountain crush of the class described coinas prising a handle portion having a tube receiving socket, a tube therein, a movable cover for closing the socket and retaining the tube therein, the handle having means for receiving the open end of the paste tube, the handle having a passage communicating withsaid last mentioned means, the handle carrying a brush head, said passage having a discharge port adjacent the brush head,

and means controllable by the cover when moved for opening and closing said discharge port.

2. A fountain brush of the class described comprising a handle portion having a tube receiving socket, a tube therein, a cover for closing the socket and retaining the tube therein, the handle having means for receiving the open end of the paste tube, the handle having a passage communicating with said last mentioned means, the handle carrying a brush head, said passage having a discharge port. adjacent the brush head, said cover being pivotally mounted upon said handle adjacent the brush head, and having a valve extension neck adapted to close the discharge port of said passage when the cover is in a closed position over-the socket formed in the handle, and to uncover the discharge port when the cover is in an open position.

3. A fountain brush of the class described comprising a handle portion having a tube receiving socket, a tube therein, a cover for closing the socket and retaining the tube therein, the handle having means for receiving the open end of the paste tube, the handle having a passage communicating with said last mentioned means, the handle carryinga brush head, said passage having a discharge port adjacent the brush head,

said cover being pivotally mounted upon said handle adjacent the brush head. and having a valve extension neck adapted to close the discharge port of said passage when the cover is in a closed position over the socket formed in the handle and uncover the discharge port when the cover is in an open position, and means for detachably holding the cover in a closed position upon the handle.

4. A fountain brush of the class described comprising a handle having a paste tube containing socket formed therein, said handle having a channel adapted to communicate with the open end oi a paste tube placed within said socket, said handle having a brush head, the handle having a discharge port communicating with the channel adjacent the brush head, a cover slidably mounted upon said handle to permit access to the paste tube carried within the socket, and said cover having an extension at one end for normally closing the discharge port of said channel when said cover is in a closed position uponsaid handle.
